We use /data/incremental to keep all the directories that are mounted on
the Incremental File System.
Since system_server does not have permission to dynamically create dirs
directly under /data, we create /data/incremental in init.rc.

These weak symbols are no longer necessary because we no longer
need to statically link libvndksupport.
Furthermore, these symbols are not really optional when libvndksupport is
dynamically linked. When the library is linked with --as-needed the linker
may drop the reference to libdl_android.so, which leads to a failure to boot.

This fixes two bugs in how we use fallocate(). First, using ZERO_RANGE
is a mechanism to allocate holes, not blocks. Instead we should be
passing no flags.
The reason this code worked is because of our explicit writes to the
file, which is intended to defeat lazy block allocation. This is not
necessary for F2FS with proper file pinning support, so we now skip this
when possible.
Together, these fixes improve the speed of "adb remount" when backed
by libfiemap.

d77c99ebc3 changed MappedFile to return a
bogus zero-length mapping on failure rather than nullptr. None of the
calling code was changed, though, and it seems like doing so would be a
bad idea. Revert that part of the change.
Add missing tests, and tidy up some of the logging. Also remove
single-use or obfuscatory constants from the tests.
The new "empty.zip" was created by using zip(1) to create a zip file
with one entry, then using `zip -d` to remove it.
The new "zero-size-cd.zip" was created by using zip(1) to create a zip
file containing a single empty file, and then hex editing the two byte
"size of the central directory" field in the "end of central directory
record" structure at the end of the file. (This is equivalent to, but
much smaller than, the example zip file provided by the bug reporter.)

This reverts commit 5d53bfce2d.
Reason for revert: for consistency, we've decided that for now, all code will have the same view of /storage: FUSE. Will address the TODO here later.

In recovery the user has the option to mount /system, but when a device
is updating with Virtual A/B, the _b partition may be a snapshot.
This patch introduces a helper function that satisfies the dependency of
setting up the snapshot devices required to mount /system.

When bind-mounting flattened APEX, use the apex name found in
apex_manifest.pb as the mount point, instead of the directory name which
might be different from apex name in case when the apex is overridden.
This allowed us to remove the special casing for the ART apex since we
/system/apex/com.android.art.release will be mounted to
/apex/com.android.art instead of /apex/com.android.art.release.

Add an API that does not initiate the merge, but only waits for it to
finish. It is different from ProcessUpdateState API in that it also
blocks when state == UNVERIFIED and booting from the new slot.
(ProcessUpdateState immediately returns in this case).
This is useful for android.os.UpdateEngine.CleanupSuccessfulUpdate().

Factor out obscure logic that reads boot indicator path.
GetCurrentSlot() returns three states:
- None (read failure)
- Old (before reboot)
- New (after reboot)
Use these "logical" slot values for simpler code.
